Define computer virus?
A computer virus is a type of malicious software (malware) that is specifically designed to replicate itself and spread from one computer to another. Viruses
can be transmitted through email attachments, infected software downloads,
or by being transferred from an infected device to a clean device via a
removable drive or network.
When a virus infects a computer, it can cause a variety of problems, such as slowing down the system, corrupting data, or displaying unwanted messages
or ads. Some viruses are designed to steal sensitive information, such as
login credentials or financial data, while others are designed to cause
damage to the system or disrupt its normal functioning.
To protect against viruses, it is important to install and regularly update antivirus software on your computer. It is also important to be cautious when opening
email attachments or downloading software, and to avoid visiting unknown or untrustworthy websites. If you suspect that your computer may be infected
with a virus, you can try running a scan with your antivirus program or seek
the help of a professional.
